BeRTOS Embedded Survey Summary 2011

"Microcontroller firmware development and embedded RTOS" is an initiative that analyses and registers behaviours in the embedded world,
identifying the most used RTOS, working tools and the most popular trends in the market sector.

19. During your last year projects, where did you get the drivers for your peripherals(serials, ADC, PWM, I2C, etc...)? Response Response Percent Count I wrote them from scratch 69,0% 49 I already had previous code 62,0% 44 developed for other projects They were supplied by the microcontroller/demoboard 47,9% 34 manufacturer Purchased on the Internet 8,5% 6 Downloaded for free from the 45,1% 32 Internet Already integrated in my RTOS 29,6% 21 Already integrated in my 23,9% 17 compiler/IDE Other (please specify) 0,0% 0 answered question 71 skipped question 2220. During your last year projects, did you have to modify/adapt the drivers?

27. What do you think about the software that comes with a microcontrollerdevelopment board (examples, libraries, compilers, RTOSes, etc...)? Response Response Percent Count It is fundamental for development: in this way you 53,6% 37 can save time starting from something already done It is only a demo: firmware development tools are evaluated 39,1% 27and choosed separately in order tofind the best solution on the market Other (please specify) 7,2% 5 answered question 69 skipped question 2428.
